That's between 1999 and 2006.

I regularly download the files the RIRs publish on their FTP sites  
and generate statistics from them at http://www.bgpexpert.com/ 

If you go to that page it will tell you the number of addresses  
currently given out by IANA or the RIRs to end-users or ISPs:

2465.82 M

Fill in "US" under "Country" and it will say:

1379.23 M

This means that 55.93% of the address space currently in use is held  
by the US according to the RIRs.
